Description

Technical Field

[0001] The utility model relates to the technical field of plastic particle melting devices, in particular to a melting preheating device for plastic particles. Background Art

[0002] Plastic particles refer to small granular substances made by mechanical shearing, extrusion, thermoplastic processing and other methods under certain pressure and temperature conditions. They are usually renewable and highly plastic materials and are often used to make various plastic products. Because the manufacturing process of plastic particles may cause pollution, many plastic manufacturers and related companies are taking environmental protection measures to reduce the impact on the environment, such as using renewable energy production.

[0003] Among them, the melting of plastic particles is an important link in the plastic processing process, which involves the transformation of plastic from solid to liquid. The melting process of plastic particles can be divided into three stages: solid, semi-molten and completely melted. In the solid stage, the plastic particles are uniformly transparent or translucent; as the temperature rises, the particles begin to enter the semi-molten state, at which time a liquid melt layer will form on the surface of the particles, and melting will also begin to appear inside the particles; when it reaches the completely melted state, the surface of the particles completely becomes liquid and the inside is also completely melted. At this time, the plastic particles have the conditions for making various plastic products.

[0004] Currently, when melting plastic particles, the plastic particles need to be placed in a melting device first, and then heated by a heating device. The heat energy is gradually transferred to the inside of the plastic particles. As the temperature increases, the plastic particles change from a solid state to a semi-molten state and finally to a completely melted state, thus completing the melting of the plastic particles.

[0005] However, when melting plastic particles, since the current melting is carried out by heat transfer to melt the plastic particles, and the heat transfer is also affected by many factors, the working efficiency of melting the plastic particles will be reduced. Utility Model Content

At the same time, through the fit between the hook and the rotating shaft, when the melted plastic particles in the barrel body are discharged, the hook can be hung on the outer surface of the rotating shaft, so the position of the movable plate is fixed, so that the discharge port is in an open state, which is convenient for discharging the melted plastic particles in the barrel body.
